Hello Polodegard.
My name is Jenny, here in the freelance realm I work as an editor, writer, and business consultant. I am more than ready to help you give a new life to that "old" stage play.
As editors we don't like to sell stage plays because they simply don't sell. As a matter of fact, the idea of turning the stage play into an ebook is absolutely amazing. Actually your brief outline is very catchy and interesting, I would love to give a new life to the stage play without forgetting about your audience and the plot line.
I will be available to start next week, meanwhile, if you have any questions feel free to contact me.
Best wishes,
Jenny
